OPTIONS

22       -h or --help

28       -q or --quiet
29              Do not print informal notifications about actions taken  to  the
30              console.    By   default  a  short  description  of  each  qdisc
31              added/update/deleted will be printed to the console. This option
32              disables this behaviour.
33
34       -d or --dev=DEV
35              Network device the qdisc is attached to.
36
37       -p or --parent=ID
38              Identifier  of the parent qdisc/class this qdisc is attached to.
39              The identifier can be specified as classid, name or one  of  the
40              special values "root" or "ingress".
41
42       -i or --id=ID
43              Identifier of qdisc. It can be specified as classid or name.
44
45
46   nl-qdisc-add Options
47       --update
48              Update qdisc if it already exists, otherwise attempting to add a
49              qdisc which already exists will result in an  error.  This  does
50              not include changing the type of the qdisc, use --replace if you
51              wish to do so.
52
53       --replace
54              Replace or update qdisc if it already exists. Same behaviour  as
55              --update  but  will  completely  replace  the qdisc if it exists
56              already.
57
58       --update-only
59              Update an existing qdisc but do not create it  if  it  does  not
60              exist.
61
62       --replace-only
63              Update  or  replace an existing qdisc but do not create it if it
64              does exist.
65
66
67   nl-qdisc-delete Options
68       --interactive
69              The interactive mode requires confirmation by the user for  each
70              qdisc  deleted.  It  will print a prompt for each qdisc matching
71              the provided filter and requires the user  to  answer  'y'es  or
72              'n'o.
73
74       --yes  Make  the  default answer for interactive prompts be 'y'es. This
75              option is also required to delete  all  qdiscs  on  all  network
76              devices.
77
78       -k or --kind=TYPE
79              Only delete qdiscs of this type.
80
81
82   nl-qdisc-list Options
83       --details

85
86       --stats

88              will also turn on detailed information automatically.
89
90       -r or --recursive
91              List all TC objects recurisvely attached to all qdiscs  matching
92              the filter.
